Galactic Center
The Galactic Center and the surrounding Central Molecular Zone comprise the most active star formation region in the Milky Way... (Image Created by Adam Ginsburg:Univ of Colorado - Boulder, Courtesy of Dr. James Aguirre)

Kummer Surface
Graph of the real points of a quartic Kummer surface in a three dimensional projective space. This is a singular surface of type K3 which has 16 singular points.(courtesy of Dr. Tony Pantev).

Computer simulation of tethered particle motion
Representative frame from a computer code that computed the distribution of positions of a micrometer-size bead tethered to a surface by a single DNA molecule. (Courtesy of Kevin Towles/Philip Nelson).
Trajectory of DNA on a mica surface courtesy of Dr. Philip Nelson
Trajectory of DNA on a mica surface
Actual shape assumed by a single molecule of DNA resting on an atomically flat surface, visualized using atomic force microscopy. The vertical direction has been exaggerated; actually the molecule is as tall as it is wide (Courtesy of Fernando Moreno, Delft University/Philip Nelson).
Computer simulation of DNA looping courtesy of Dr. Philip Nelson
Computer simulation of DNA looping
Representative frame (one of about ten billion) from a computer code that computed the probability for two segments of DNA to come spontaneously into the proper positions for a DNA binding protein to tie them into a loop. DNA looping is a key event in gene regulation in bacteria.(Courtesy of Kevin Towles/Philip Nelson)

Algorithm for Solving Maxwell's Equation
These are plots for the absolute value of matrix elements used in a new algorithm for solving Maxwell's equation in the exterior of the perfectly conducting sphere. The dark blue dots mark the locations of spurious resonances. (Courtesy of Charles Epstein & Leslie Greengard)
